All Airstars have three main components: Electrical (Power and bulb options for coverage and color temperature.), Accessories (Stands, Sand Bags, Skirts, Reflectors, Etc.), and Envelopes. Our film envelopes are handcrafted with integrated reflector tops, increasing the light output by at least 30%. Airstars are handmade with finely engineered pattern designs, the highest quality sewing technology, helium and air-tight silicone seals and coatings, as well as the most durable anti-UV fabrics. You can easily see the difference between an Airstar and the inferior quality of copycat products.
